I am a newbie to this, and hope someone can give guidance.  We are trying to perform what appears to be a very simple ldap connection.  I've researched and see that most examples for connecting are the same through .NET, however, we continue to get the message "Logon failure: unknown user name or bad password."  I know the server name and path are correct, and I know the user name and password are valid.  Both are used in another application that was written in Coldfusion, and the connection works.  Are there any hidden attributes that need to be set, or anything I need to set up in the configuration file?  As I said, I'm a newbie to this area, so any tips would be greatly appreciated.  Here is what my code looks like.  I've replaced the server name, user name, and password, but the structure is the same:
